I know there has been been some discussion here and there about what kind of lubricant to use in the LM4 (and GBBs in general). I was just curious as to what people use in there guns and what works well.

I know KWA recommends 30wt silicone oil. My local shop that specializes in GBBs only was recommending this stuff:http://www.blowbacka..._p/lube-eas.htm
They say its safe for the o-rings too. Anyone have any experience with this stuff?

I experimented with Frog Lube when I first got my LM4 and it was excellent. To the point that I put it on a YouTube video and recommended it to anyone I could. I know Dos Santos also used Frog Lube and he loves it as well.

It's great because it lubricates the gun without the risk of swelling the hopup bucking.

I use Frog Lube on my real steal firearms. To be honest, I havent tried it on my LM4 or my WE SCAR. Its lubricating properties are at its best when warmed up from firing. Since airsoft guns do not get warm/hot with use, I never thought of trying it.

All that said, its AWSOME on my Glock, Sig, Ruger and several Rifles. When the barrel gets hot, the FL goes from being waxy to liquid. WORKS GREAT.

If you guys could let me know what you guys use that would be great.

I have that same stuff..and i have this "other" stuff..the lube from BBA they say is specially formulated for GBB's. I also have this other oil thats made for sewing machines/firearms. I cant prove it but the consistency and look is the same as the BBA lube except the BBA lube is tinted blue, and my sewing machine oil is clear. And my guess is that BBA dyed their lube to make it "different" they are charging $8 for their lube and my lube costs $30 a gallon. And my lube doesnt swell oring or weaken them either like silicone oil does..i also use frog lube for all the metal parts. Honestly..id just go buy froglube and forget about the "end all solution" re-bottled sewing machine oil...or go buy some sewing machine oil!

It couldn't be a bad thing per se. It would adhere to the metal very well. I don't think it would add a lubrication value though for all the trouble of getting to the gears. Let us know if you try it though!

yea i was just thinking, esp for high speed setups theres a significant amount of heat generated from the gears. i figure i may try it next time i break open a gearbox for maintenance/repair. also to consolidate as many materials as possible, instead of buying 2-4 different types of lube.

I use frog lube, and one of the major pluses beyond it's excellent lubrication is its anti corrosion properties. I played a game in the rain a few months ago, using my lm4 (which I had completely disassembled and treated every metal part with frog lube and hair dryer) and my mp7 (which had not been frog lubed). The mp7 started corroding within an hour, the lm4 had no corrosion issues at all.

Usually most of us use silicone oil on the o-rings of GBBs and AEGs alike. This is primarily to avoid and resistance issues that can occur with higher viscosity greases. That said, give it a try, measure your FPS and ROF before and after. Make sure the cylinder is returning to it's proper position within the bolt and report back. After all, assuming it's okay for o-rings, you can always clean it off and use something else if you loose performance.

Start with a smaller bottle! Should just take a couple of drops of lube. I've not been thru a 50ml (1.7oz) bottle of silicone oil yet for my half dozen airsoft guns. An 8oz (237ml) bottle of Frog Lube is likely a lifetime supply for airsoft use.

Frog Lube claims to be a CLP (cleaner, lubricant, preservative) but I've no clue if it meets the milspec for CLP. Also claims to contain no petroleum or water and be food grade and biodegradable.

Stick with the manufacturers recommendation for the o-rings. I would not use Frog Lube for o-rings as the application process requires you heat the surface and then apply the lubricant. You don't want to heat up an o-ring; you would probably distort it. Stick with silicone oil for o-rings.
